The first graphical browser was ____.

The first graphical browser was Mosaic. Launched in 1993, Mosaic is significant because it made the World Wide Web accessible to a broader audience through its user-friendly interface that integrated graphics alongside text. This was a revolutionary step forward from the primarily text-based browsers that preceded it, allowing users to see images and navigate through the web visually rather than through command-line or text-only interfaces.

Mosaic played a crucial role in popularizing the web, ultimately leading to the development of other graphical browsers, notably Netscape Navigator, which was built on some of the foundations established by Mosaic. The advent of Mosaic marked the transition of the Internet from a tool used mainly by academics and researchers to one that began to engage the general public.
